At the moment of instantiation the FP options may be different from the default values, defined by command-line option. In such case FP attributes would have unexpected values. For example, the code: template <class C> void func_01(int last, C) { func_01(last, int()); } void func_02() { func_01(0, 1); } #pragma STDC FENV_ACCESS ON caused compiler crash, because template instantiation takes place at = the end of translation unit, where pragma STDC FENV_ACCESS is in effect. = As a result, code in the template instantiation would use constrained intrinsics while the function does not have StrictFP attribute. To solve this problem, FP attributes in Sema must be set to default values, defined by command line options. This change resolves https://github.com/llvm/llvm-project/issues/6354= 2.
